I'm not sure what "both sides" of pressing someone's hand into their arm until their wrist snaps is. Nor am I sure what "both sides" of someone being hit with truncheons until they convulse and stop moving is.
Are you saying the footage is faked or something else?
You were writing about images being posted out of context. I'm still struggling to determine the context that would make these things (or other things, like slowly sinking your thumbs into a hospital patient's eyes while they're restrained) OK. You've replied by discussing other incidents, which doesn't answer the question.
